Biamp DS1320 Sound Masking Emitter
The DS1320 is an emitter equipped with a 1.25-inch driver, capable of simultaneously playing sound masking and clear paging audio. It achieves higher SPL and a wider frequency range compared to conventional direct field type emitters. Operation requires the Qt X 800/805 series.

Frequency Response and Beamwidth
The document includes graphs illustrating the frequency response for sound masking and the beamwidth (-6 dB) of the emitter. The sound masking frequency response covers a range from 100 Hz to 10 kHz, showing a relatively flat output. The beamwidth graph indicates the directional characteristics of the sound, showing a wide dispersion pattern.
